In 1966, the French company Nord (later part of Aérospatiale) built two Cadets, each powered by two 317 shp Allison T63-A-5A engines. The Nord 500 Cadet was 22 ft long and 20 ft wide, weighed only 2,760 lb and used two relatively large five-bladed ducted propellers. On the exit end of the ducts, four control vanes in a diamond shape controlled pitch (collectively) and yaw (differentially). This configuration was selected to try to expand the airflow in hover and compress it during horizontal flight.
The first aircraft was used for static tests while the second made a tethered hover on 23 July 1968. It was canceled without being tested further.
